Flashcard (Part 1)-Symmetry and Tessellations

Front

What is a line of symmetry?

Back

A line of symmetry is a line that divides a shape into two identical parts that are mirror images of each other.

Front

How many lines of symmetry does a regular hexagon have?

Back

6

Front

What is tessellation?

Back

Tessellation is a pattern made of one or more shapes that fit together without any gaps or overlaps.

Front

Which shapes can tessellate?

Back

Regular triangles, squares, and regular hexagons can tessellate.

Front

Which shape will NOT tessellate?

Back

Regular pentagon will NOT tessellate.

Front

What is rotational symmetry?

Back

Rotational symmetry is when a shape can be rotated around a central point and still look the same at certain angles.

Front

How many degrees can a regular hexagon be rotated to show rotational symmetry?

Back

A regular hexagon can be rotated 60 degrees, 120 degrees, 180 degrees, 240 degrees, 300 degrees, and 360 degrees.

Front

What is the difference between reflectional symmetry and rotational symmetry?

Back

Reflectional symmetry involves a mirror line, while rotational symmetry involves turning the shape around a point.

Front

Which letters have line symmetry?

Back

Letters H, A, and X have line symmetry.

Front

Which letter does NOT have line symmetry?

Back

The letter Z does NOT have line symmetry.
